How does acid precipitation affect land and water organisms

Acid has a different chemical reaction than the water molecules. So when animals and other organisms swim, drink, or eat out of a body of water with acid precipitation in it it will probably kill them. Acid is in lemons and other foods we eat and drink so what kind of acid is it talking about? Is it talking about a harmful substance that would kill anything or a substance that is edible.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
